Hello Oxmart,
Can you please clarify why do you think recursive depth is not right?
CURSOR #4 seem to be recursive SQL with the depth of 1.

The way I had understood the traces to display was due to the way Oracle
dealt with recursive SQL.
If you have an SQL statement that needs to do two actions, for example an
insert that fires a trigger that updates some row in another table. Before
the insert can finish the trigger must finish. So in this case
insert dep 0
|
trigger dep 1
|
update dep 2
The impression I got was when looking at the events 10046 trace data one
would see:
Parsing in Cursor .... dep=2 ...
.....
....
Parsing in Cursor ..... dep=1 ...
....
....
Parsing in Cursor .... dep=0....
In a number of SQL's I did see this pattern, however in the trace data I
provided this was not the case:
PARSING IN CURSOR #3 len=238 dep=0 uid=60 oct=3 lid=60 tim=43164556233
hv=4211298066 ad='7157da00'
select distinct c.name, s.name, s.salesperson_id
from customer c join orders on c.cust_nbr = orders.cust_nbr
join salesperson s on orders.salesperson_id = s.salesperson_id
where c.name = 'Crimson Medical Inc.'
order by s.name, c.NAME
END OF STMT
followed by:
PARSING IN CURSOR #4 len=116 dep=1 uid=0 oct=3 lid=0 tim=43164909064
hv=431456802 ad='70797038'
select
o.owner#,o.name,o.namespace,o.remoteowner,o.linkna me,o.subname,o.dataobj#,o.
flags from obj$ o where o.obj#=:1
END OF STMT
this case seems to be backwards from the way I thought it should work.
